match: fix NameError 'pat' on overflow of regex pattern length 'pat' was renamed to 'regex' in 9d28fd795215.

color: add missing handling of stderr capture introduced by 350dc24a553d It wouldn't raise exception without this change, but _bufferstates was wrong because of missing _bufferstates.pop() in colorui.popbuffer().

hgweb: replace excanvas.js with a newer version The current version of excanvas is unknown. Substitute it with the latest version from the excanvas website: http://code.google.com/p/explorercanvas/ Instead of using the "compiled" version, just use the readable one.

httppeer: reintroduce _abort that accidentally was removed in 167047ba3cfa Including the missing test coverage that would have caught it.

bundle2: gracefully handle hook abort We make sure any exceptions raised during the whole span of handling bundle2 processing are decorated. This let us catch exceptions raised by hooks prior to transaction commit.

bundle2: gracefully handle PushRaced error during unbundle Same drill again. We catch the PushRaced error, check if it cames from a bundle2 processing, if so we turn it into a bundle2 with a part transporting error information to be reraised client side.

bundle2: add an error message to push race error Errors with no explanations makes my uncle Bob sad.

bundle2: fix raising errors during heads checking If the heads on the server differ from the ones reported seen by the client at bundle time, we raise a PushRaced exception. However, the part raising the exception was broken. To fix it, we move the PushRaced class in the error module so it can be accessible everywhere without an import cycle. A test is also added to prevent regression.

bundle2: gracefully handle UnknownPartError during unbundle Same as for Abort error, we catch the error, encode it into a bundle2 reply (expected by the client) and stream this reply. The client processing of the error will raise the exception again.

bundle2: catch UnknownPartError during local push When doing local push, UnknownPartError from the server will be raised directly to the client. We need to catch them too.

bundle2: catch UnknownPartError during pull We narrow the exception catching while pulling.

bundle2: catch UnknownPartError during push We narrow the exception catching while unbundling the push reply.

bundle2: use a more specific UnknownPartError when no handler is found KeyError is very generic, we need something more specific for proper error handling.

bundle2: make error testing more modular We have more than Abort to test.

bundle2: gracefully handle abort during unbundle Clients expect a bundle2 reply to their bundle2 submission. So we catch the Abort error and turn it into a bundle2 containing a part transporting the exception data. The unbundling of this reply will raise the error again.

bundle2: decorate exception raised during bundle processing This is a small hack to help us do some graceful error handling in bundle2 without major refactoring. See embedded comment for details.

histedit, i18n: replace '+' with concatenation to make hggettext happy

commands: fix typo in --graph description

revset, i18n: add translator comment to "only"

merge: improve notes for listing the bids for ambiguous merges

merge: tell the user when we are using bid merge Bid merge is a new rarely used feature that the user explicitly enabled - we should tell/warn when the user actually is using it, just like we tell when we not are using it. Give a message like note: merging 3b08d01b0ab5+ and adfe50279922 using bids from ancestors 0f6b37dbe527 and 40663881a6dd

merge: fix stray character in bid merge message

tests: better test coverage for bid merge Martin Geisler's test case revealed the previous message argument error.

merge: fix wrong number of arguments for bid merge message

merge: fix test failures with new merge code on OS X The case collision checker was missing a op entry for 'k'eep.

obsolete: fix one-element tuple in module docstring

obsolete: let N denote number of obsoleted changestes in a marker The number of obsoleted changesets is referred to as N later in the docstring.

obsolete: fix language and grammar in module docstring

churn: compute padding with unicode strings Most UTF-8 aware terminals convert multibyte sequences into a single displayed characters. Because the first column is padded by counting bytes, the second column is not perfectly aligned in the presence of non ASCII characters.
